Introduction: Why Track Replacement Matters
Replacing a track on an excavator or other tracked machinery in the field can be a challenging task, but it's essential for maintaining the performance and safety of the equipment. Tracks are critical components that ensure proper traction, stability, and performance on various terrains. When a track becomes damaged or worn out, it is important to replace it promptly to avoid further complications and downtime.
This article provides a step-by-step guide to replacing a track in the field, helping operators tackle the job efficiently.
Tools and Equipment Needed
Before beginning the track replacement, ensure you have the necessary tools and equipment for the job:
Step 1: Safety First
Before attempting any work, ensure the machine is safely parked on a flat, stable surface. Lock the tracks in place to prevent movement. It’s essential to follow all safety protocols and wear the necessary protective gear. Make sure the equipment is turned off, and all hydraulic pressures are released to avoid accidents.
Step 2: Lift the Equipment
Using a hydraulic jack or a lifting device, raise the equipment to relieve the weight from the track. Depending on the size of the machine, you may need to use a lifting crane or a dedicated lifting device.
Most tracked equipment uses a tensioning system that keeps the track tight. You’ll need to loosen the tension in the track before removal. This is often done by releasing tension on the track adjuster. Be cautious and follow the manufacturer's instructions when performing this step.
Once the track tension is released, it’s time to remove the old track. Start by removing any protective guards or covers that may be obstructing the track. Depending on the design of your machine, you may need to remove the track rollers or idlers.
Step 5: Inspect Components
Before installing the new track, thoroughly inspect the sprockets, rollers, and idlers for wear or damage. Replacing the track without checking other components can lead to premature wear of the new track. If you find any worn-out parts, consider replacing them at this time.
Now that the old track is removed and the components are inspected, it’s time to install the new track. Carefully position the new track around the sprockets and rollers.
Step 7: Reinstall the Track Pins
Once the new track is positioned correctly, reinsert the track pins. Use a hammer and a punch or a pin-puller tool to secure the pins tightly. This will lock the track in place and ensure it doesn’t come loose during operation.
Adjust the track tension to ensure it is neither too tight nor too loose. Follow the machine’s manual for the correct tension specifications. Proper track tension is essential for optimal performance, and adjusting it correctly will prevent unnecessary wear on the track and other components.
After the track is installed and tensioned, lower the machine back to the ground. Start the engine and slowly drive the equipment forward to test the track’s alignment and tension. Make sure everything moves smoothly and the track operates properly.
If the track does not perform as expected, double-check the tension, alignment, and components for any issues.
Conclusion: Ensuring Longevity
Replacing a track in the field is a demanding task, but with the right tools, preparation, and careful attention to detail, it can be done successfully. Taking the time to inspect and replace worn-out components will help extend the life of the new track and keep your equipment running smoothly.
By following these steps, you can ensure a proper and efficient track replacement process, keeping your machine in good condition and minimizing downtime on the job site. Regular maintenance and timely track replacement are key to the longevity of your equipment.

Tools and Equipment Needed
Before beginning the track replacement, ensure you have the necessary tools and equipment for the job:
- Hydraulic jacks or a machine with lifting capacity
- Track press or track adjusting tools
- Wrenches and sockets
- Track pin puller
- Safety equipment (gloves, steel-toed boots, safety glasses)
- Grease or lubricant for parts
- Replacement track (properly sized for your equipment)
Step 1: Safety First
Before attempting any work, ensure the machine is safely parked on a flat, stable surface. Lock the tracks in place to prevent movement. It’s essential to follow all safety protocols and wear the necessary protective gear. Make sure the equipment is turned off, and all hydraulic pressures are released to avoid accidents.
Step 2: Lift the Equipment
Using a hydraulic jack or a lifting device, raise the equipment to relieve the weight from the track. Depending on the size of the machine, you may need to use a lifting crane or a dedicated lifting device.
- Pro Tip: It is important to lift the equipment only high enough to allow enough space to remove the track. You don’t need to raise it unnecessarily high, which could compromise stability.
Most tracked equipment uses a tensioning system that keeps the track tight. You’ll need to loosen the tension in the track before removal. This is often done by releasing tension on the track adjuster. Be cautious and follow the manufacturer's instructions when performing this step.
- Pro Tip: If your machine has a hydraulic track tensioning system, this can be done by releasing the hydraulic pressure. If it’s a manual system, use a wrench or socket to adjust the tensioner.
Once the track tension is released, it’s time to remove the old track. Start by removing any protective guards or covers that may be obstructing the track. Depending on the design of your machine, you may need to remove the track rollers or idlers.
- Track Pin Removal: Use a track pin puller to remove the pins that hold the track together. Be mindful of the direction in which the pins need to be pulled out to avoid damaging the track or components.
Step 5: Inspect Components
Before installing the new track, thoroughly inspect the sprockets, rollers, and idlers for wear or damage. Replacing the track without checking other components can lead to premature wear of the new track. If you find any worn-out parts, consider replacing them at this time.
- Pro Tip: Check the alignment of the sprockets and the tensioning system. If these parts are misaligned or damaged, they may cause issues with the new track.
Now that the old track is removed and the components are inspected, it’s time to install the new track. Carefully position the new track around the sprockets and rollers.
- Pro Tip: Make sure that the track is aligned properly with the sprockets. Misalignment can cause premature wear on the new track.
Step 7: Reinstall the Track Pins
Once the new track is positioned correctly, reinsert the track pins. Use a hammer and a punch or a pin-puller tool to secure the pins tightly. This will lock the track in place and ensure it doesn’t come loose during operation.
- Pro Tip: Apply some grease or lubricant to the pins before reinstalling them. This helps prevent rusting and facilitates easier removal during future replacements.
Adjust the track tension to ensure it is neither too tight nor too loose. Follow the machine’s manual for the correct tension specifications. Proper track tension is essential for optimal performance, and adjusting it correctly will prevent unnecessary wear on the track and other components.
- Pro Tip: Over-tightening the track can lead to excessive wear on the components, while under-tightening can result in poor traction and efficiency.
After the track is installed and tensioned, lower the machine back to the ground. Start the engine and slowly drive the equipment forward to test the track’s alignment and tension. Make sure everything moves smoothly and the track operates properly.
If the track does not perform as expected, double-check the tension, alignment, and components for any issues.
